[amibroker] Re: Help needed on a simple code:

["nebt1" <nebt1@xxxxxxxxx>]

Hi David,
Just find out that idea with color does not work. When I have high 
say at 16:10, it plots that high the next day. So code must be a 
function of time and not color. Hope some one has solution for this 
simple code.
Tia, Tom
